i play real media and mp3s. For both the problem is the same. Whem i play
mp3 is very low and the commands are executed seconds after.
I don't understand why if i change sound card i have no problems.
Could it be because the sound chipset i use has very poor drivers? I can't
mix channels for example and so i can't execute 2 or more sounds at the
same time.

thanks
